soft wash surfactant in LaGrange

In LaGrange, this comes up on historic-district houses, college-side streets, and the larger lots toward Vernon Road and Callaway. LaGrange clay does not rinse off a driveway with a garden hose, and shaded brick grows a green film by late summer. On a tall or shaded wall, dwell time is the whole point. If the mix runs off in ten seconds, you paid for a rinse.

January here is gutters full of oak, a porch that needs to look right for guests, and the odd jobs that got postponed all year.

Sodium hypochlorite in plain water beads and runs. A surfactant lowers the surface tension so the solution sheets onto the siding and stays there long enough to work. Some are thicker, so they hang on vertical surfaces. That is why a soft wash can look like it is “sitting” on the wall. It is supposed to.

The surfactant is not the cleaner. It is the delivery. The killing of algae and mildew is still the hypochlorite. When the dwell is done, both are rinsed. We do not leave a sticky film as a “protectant.” If a product claims to seal the house against future mildew because of the soap, ask to see that in writing. We will not say it.

Overspray is why the surfactant matters to your plants as much as to the wall. A mix that clings to the house also clings to a dry leaf. We wet the plantings first so they are full of plain water, keep the spray on the wall, and rinse the landscape when we rinse the house.

The full explanation, without the town attached, is the why a soft wash needs a surfactant article. The town does not change the chemistry. It changes the houses, the shade, and the clay.
